Driving and Operating 9-65
The Tow/Haul Mode may be used if
the transmission shifts too often.
SeeTow/Haul Mode on page 9‑33.
When towing at high altitude on
steep uphill grades, consider the
following: Engine coolant will boil at
a lower temperature than at normal
altitudes. If the engine is turned off
immediately after towing at high
altitude on steep uphill grades, the
vehicle may show signs similar to
engine overheating. To avoid this,
let the engine run while parked,
preferably on level ground, with the
automatic transmission in P (Park)
for a few minutes before turning the
engine off. If the overheat warning
comes on, see Engine Overheating
on page 10‑18.Parking on Hills

the trailer attached can be
dangerous. If something goes
wrong, the rig could start to move.
